DILATOR.

SPECIFICATION forming part Of Letters Patent N0. 719,487, dated.February 3, 1903. Application led September 16, 1901. Serial No. 75,443.(No model.)

To aZZ whom t rnag/ conccrm Be it known that I, WILLIAM E. MINOR, acitizen of the United States of America, residing in Kansas City, in thecounty of Jackson and State of Missouri, have invented a new and usefulImprovement in a Combined Dilator and Ointment-Injector, of which thefollowing is a specification, reference being had therein to the`accompanying drawings, forming a part thereof.

My invention relates to improvements in dilators used for dilatingorifices of the human body. Ordinarily the dilation is acquired bydegrees by using instruments vary- Ing in diameter.

One of the objects of my invention is to provide a dilator in which thedifferent degrees of dilation may be attained with the use of a singleinstrument. f This is achieved by giving the dilator the form of aplurality ot cylinders having their axes in line and abutting ends, thelarger of the abutting ends tapering tothe size of the smaller. Thecylinders being of different diameters afford a means for varying thedegree of dilation, the smaller cylinders only being at first inserted.

My invention provides, further, means for applying heat to theinstrument at the time of its insertion, and thus obtaining the benefitof the healing properties of heat upon the parts operated upon.

My invention provides, further, in combination with the foregoingfeatures, a chamber in the dilator for the reception of medicinalmaterial, one or more openings leading from the chamber to the exteriorof the dilator, and means for ejecting the said material from the saidchamber through the said opening or openings.

My invention provides, still further, a chamber for the reception of aliquid heating material, such as hot water, so disposed as to heat thedilator and also the medicinal material held in the chamber provided forsuch material.

Other features of construction are hereinafter fully described andclaimed.

In the accompanying drawings, which illustrate one form of my inventiondesigned for the use of hot water as a heating material, Figure lis acentral longitudinal sectional view. Fig. 2 is a side elevation View.Fig. 3 is a cross-sectional view taken on the dotted line a b of Fig. l.

Similar letters of reference indicate similar parts.

The body of the dilator comprises the three cylindrical tubular sectionsA, B, and C, having diierent diameters and abutting ends, the abuttingends of the larger cylinders tapering to the size of the smaller. Thesmaller cylinder C extends concentrically through the cylinders A and B,thus providing an annular chamber D for the reception of a heatingsubstance, such as hot water. The outer end of the dilator is providedwith an annular plug E, which tightlyiits'the inner wall of the cylinderA and the rear end of the tube C. Two nipples F and G are provided inopenings made `therefor in the plug E. To these two nipples areconnected rubber tubes, (not shown,) which convey the Water to and fromthe chamber D. The opening in the discharge-nipple is preferably smallerthan in the other, so that Water will be retained in the chamber D andnot flow therefrom as `fast as admitted thereto. `A conoidal cap H issecured in the inner or forward end of the cylindrical tube C, thuspermitting the easy insertion of the dilator where it is to be employed.A chamber l is thus formed Within the tube C, having one end open andadapted to receive through the open end suitable medicinal material,such as an ointment or salve. In the body of the dilator are providedopenings J, leading from the chamber I to the exterior of the dilatorand located preferably near the cap H. Within the tube C is closelyfitted a reciprocative piston K, secured to the inner end of a plungerL, the outer end of which projects outside the chamber I and has mountedthereon a button or linger-hold M. To prevent cramping of the piston inthe tube, a supplemental guiding-disk N may be mounted upon theplunger-rod L.

In operatingmy invention the patient first inserts in the orifice to betreated the smaller end C of the dilator, the medicinal ointment havingbeen previously forced to the inner end of the chamber I by the pistonK. I-Iot water is then permitted to flow through the chamber D, thedegree of heat applied being IfO regulated by regulating the amount ofWater permitted to flow through the chamber at a given period of time orby regulating the temperature of the Water admitted. The piston K isthen forced inward by applying pressure to the button M, thus forcingthe medicinal material, which is preferably of a plastic nature, throughthe openings J, after Which it comes into contact with the flesh of theparts to be treated. After the patient has used the instrument severaltimes the orifice treated becomes sufficiently enlarged to permit theinsertion of the dilator far enough for the entrance into the orifice ofthe next larger cylindrical portion B, and continued insertions of thisportion of the dilator still further enlarges the orifice until theportion A of the dilator can be inserted.

Various modifications can be made Without departing from the spirit ofmy invention.

Having thus described my invention, What I claim, and desire to secureby Letters Patent, is-

1. A dilator provided with a chamber for the reception of a medicinalsubstance, an opening leading from the said chamber to the exterior ofthe dilator, means for ejecting the said substance from the said chamberthrough the said opening, and a chamber for the reception of a heatingmaterial adjacent to but disconnected interiorly from the first chamber,substantially as described.

2. A dilator provided with a chamber for the reception of a medicinalsubstance, an Opening leading from the said chamber to the exterior ofthe dilator, means for ejecting the said substance from the said chamberthrough the said opening, and a chamber for the reception of a liquidheating material adjacent to but disconnected interiorly from the firstchamber, substantially as described.

3. Adilator provided with a chamber for the reception of a medicinalsubstance, an opening leading from the said chamber to the exterior ofthe dilator, means for ejecting the said substance from the said chamberthrough the said opening, means for heating the body of the dilator, andthe dilator having the form of a plurality of cylinders With abuttingends and different diameters, the larger of the abutting ends taperingto the size of the smaller, substantially as described.

4. A dilator provided with a chamber for the reception of a medicinalsubstance, an opening leading from the said chamber to the exterior ofthe dilator, means for ejecting the said substance from the said chamberthrough the said opening, a chamber for the reception of a heatingmaterial, and the dilator having the form of a plurality of cylindersWith abutting ends and different diameters, the larger of the abuttingends tapering to the size of the smaller, substantially as described.

5. A dilator provided with a chamber for the reception of a medicinalsubstance, an opening leading from the said chamber to the exterior ofthe dilator, means for ejecting the said substance from the said chamberthrough the said opening, and a chamber encircling the said chamber butinteriorly disconnected therefrom for the reception of a liquid heatingmaterial, substantially as described. Y

6. A dilator provided With a chamber for the reception of a medicinalsubstance, an opening leading from the said chamber to the exterior ofthe dilator, means for ejecting the said substance from the said chamberthrough the said opening, a chamber encircling the said chamber for thereception of a liquid heating material, and the dilator having the formof a plurality of cylinders With abutting ends and different diameters,the larger of the abutting ends tapering to the size of the smaller,substantially as described.

7. A dilator provided With a chamber for the reception of a medicinalsubstance, an opening leading from the said chamber to the exterior ofthe dilator, a reciprocal plunger in the said chamber for ejecting thesaid substance from the said chamber through the said opening, a chamberadjacent to butinteriorly disconnected from the rst chamber, and thedilator having the form of a plurality of cylinders with abutting endsand different diameters, the larger of the abutting ends tapering to thesize of the smaller, substantially as described.

In testimony whereof I have signed my name to this specification inpresence of two subscribing Witnesses.
